A female office worker gets hooked on sexually teasing her overly serious, younger boyfriend.
72 main pages

Mainly features femdom content like a blowjob and prostate teasing, but the second half features hardcore sex between the couple!

Though this is a sequel, you can read it just fine on its own.
It'd be great if you read the original, though!

[Story]
Misaki (24) and her boyfriend Yuu (21) have been dating for a year, but have known each other since they were very young. She should have been satisfied with normal sex, but lately she's gotten really into making him moan.

One day she gets chosen to participate in a recruiting event at Yuu's university. Everything went great, including her speech, but at the after party she ran into a weird old guy who kept hitting on her. Luckily Yuu came to save the day, and Misaki's ever so thankful~

She drags her boyfriend into an empty classroom and shows him her best blowjob technique! It's so effective that it really knocks the wind out of Yuu's sails... but once they're back home, she's got another surprise in store. She's been wanting to try this one for a long time -- an anal toy. For men!

"I heard that a prostate orgasm is way more intense than normal, and that you can keep going after it's over..."

And so Misaki gets her wish... but don't worry, so does Yuu!
